I installed dash on ubuntu 18.04:  
pip3 install dash

Then I have a test program, test.py, and I get the following error. What is wrong?

import os, pandas as pd  
import plotly  
import dash  
import dash\_core\_components as dcc \<\<\<\<\<\<\<\<\<\<\<\<\< error here:  
Exception has occurred:SystemExit

Are you sure dash core components was installed with Dash?

It turned out that the problem was that my test program was named ‘test.py’. That is bad. I renamed it to testdash.py and now it works.
